The sweet orange is produced by a small evergreen tree which is less hardy than the bitter orange tree. It has shiny leaves, white flowers, and round fruits.

The orange, the most commonly grown tree fruit in the world, is thought to have originated in China, India, and perhaps southeast Asia, been transported to the Mediterranean by the fifteenth century, and taken to the New World by the mid-sixteenth century. Excellent sources of vitamin C, oranges also contain flavonoids that increase the body's resistance to carcinogens, allergens, and viruses while strengthing collagen (the protein that provides structure for the body's tissues).
